That's easy to deal with. The software lets me flip axis.
Unfortunately, this design will be sensitive to VCC(+5V) variations with time, temperature, individual computer's actual VCC value, and phase of the moon. We might be able to minimize this if you have room for more parts, like an op amp or two and more resistors.
The software's calibration will take care of any varience in the min and max.
This new change lets me adjust the min down to 31 and the max to 999. That's the good part. The bad part is that when I do that, the center is at 57 instead of 500.
